circRNA-disease information
Expression pattern:
DN
Associated gene: ITCH, Notch1, Wnt/beta-catenin signaling pathways, Dvl3, c-myc
Associated microRNA: miR-7, miR-24, miR-124
Biological function: inhibits cell proliferation; promotes apoptosis
Molecular mechanism: May act as a miRNA sponge (miR-7/miR-24/miR-124) and may regulate Notch1 and Wnt/beta-catenin signaling; may downregulate phosphorylated Dvl3 and inhibit c-myc expression.
Biological pathway or process:

proliferation (inhibits); apoptosis (promotes); Wnt/beta-catenin (inhibits)

Detected method:
Q
Validation methods:

RT-qPCR; Clinical Sample Validation; ROC Analysis; Survival Analysis; Transfection; CCK8; Annexin V/PI Flow Cytometry

Clinical significance:

circ-ITCH could distinguish MM patients from healthy controls (AUC 0.809); high circ-ITCH expression correlated with decreased ISS stage and prolonged PFS and OS.

Description:

circ-ITCH is down-regulated in multiple myeloma bone marrow samples and in several MM cell lines. Higher circ-ITCH expression is associated with lower ISS stage and longer PFS/OS, and circ-ITCH overexpression suppresses proliferation while promoting apoptosis in U226 cells, suggesting a tumor-suppressive role and potential biomarker/therapeutic value in MM.

Confidence score:

0.6419
